SAN LEANDRO SHORELINE DEVELOPMENT DRAFT EIR <br />CITY OF SAN LEANDRO <br />AIR QUALITY <br />There were no roadways identified within 1,000 feet of the Project site with over 10,000 average daily <br />traffic trips.42 The closest high volume roadway, Marina Boulevard, has a traffic volume larger than 10,000 <br />vehicles per day east of Aurora Drive. West of Aurora Drive, the traffic volumes are less than 10,000 <br />vehicles per day. Additionally, the Transportation Impact Analysis for the Project indicates that the twenty- <br />four hour vehicle counts for the portion of Marina Boulevard west of Aurora Drive would be less than <br />10,000 vehicles.43 Because the traffic volumes are less than 10,000 vehicles per day west of Aurora Drive <br />and the intersection of Marina Boulevard and Aurora Drive is located more than 1,000 feet from the <br />Project site, emissions of vehicles on Marina Boulevard do not require additional evaluation. <br />Lastly, the Oakland International Airport (Airport) is located approximately 1 mile northwest of the Project <br />site. Although the Airport is located over 1,000 feet away from the Project site, air emissions from aircraft, <br />ground service equipment (GSE), auxiliary power units, and fuel storage and handling have the potential <br />to impact areas over 1,000 feet away. The results of a Health Risk Assessment conducted for the Oakland <br />Airport in 2003 indicated that the incremental cancer risk to off-site residents and children in the Project <br />site area was less than 10 in one million (i.e., BAAQMD's significance threshold) and therefore, no adverse <br />health impacts are expected.` In addition, a mitigation measure requiring conversion of all diesel GSE at <br />the Airport, which accounted for 60 percent of the cancer risk, to alternative fuels by 2010 results in lower <br />incremental cancer risks than previously predicted. Based on these results, air emissions from the Airport <br />were not evaluated further. <br />BAAQMD provides screening tables that indicate predicted community risk impacts for roadways.45 The <br />results of the on-site community risk summary are provided in Table 4.2-10. <br />TABLE 4.2-10 ON-SITE COMMUNITY RISK SUMMARY <br />Project Level Risk <br />Cancer Risk <br />Chronic <br />Emission Source (per million) <br />Hazards <br />PM2.5 <br />County of Alameda Public Works 0 <br />0.0 <br />0.0 <br />Threshold 10 <br />1.0 <br />0.3 µg/m3 <br />Exceeds Threshold No <br />No <br />No <br />The results of the cancer risk screening analysis for all stationary and mobile sources within 1,000 feet of <br />the Project are less than the BAAQMD threshold of 10 in a million for a lifetime cancer risk and the non - <br />carcinogenic chronic hazard index of 1.0. In addition, PM2.5 concentrations are below the BAAQMD <br />significance threshold of 0.3 µg/m3. Therefore, the results of this screening level risk assessment, with <br />42 California Environmental Health Tracking Program (CEHTP), 2007.
